Bing announced they have dropped their trademark policy to disallow the bidding on trademarks globally, like they have in the US. The policy is going into effect March 27, 2017 in Australia, Brazil, France, Italy, New Zealand, Republic of Ireland, United Kingdom, Hong Kong, Indonesia and Singapore.
The restriction on the use of trademarks as keywords will be removed. The restriction on the use of trademarks as keywords, Bing Ads’ protection of trademarks in ad copy will remain unchanged.
Bing offers this example:
For instance, fair use of a trademark in ad copy will continue to be allowed for resellers of an authentic good or service, informational websites (such as product reviews), the ordinary dictionary use of a term, or comparative advertising (when supported by independent research).
So go ahead, big on your competitors trademarks!
